Description

A kind of method for reporting of channel condition information and device
Technical field
The application relates to mobile communication technology field, particularly a kind of method for reporting of channel condition information (CSI, ChannelstateInformation) and device.
Background technology
In wireless communication system, Frequency Division Duplexing (FDD) (FDD, FrequencyDivisionDuplex) pattern and time division duplex (TDD, TimeDivisionDuplex) pattern are widely adopted.Fdd mode is that uplink and downlink use different frequency resources to carry out the pattern communicated respectively.Tdd mode is that same frequency spectrum resource is shared in uplink and downlink, is carried out the pattern of uplink and downlink communication by temporal partitioning respectively.
Long Term Evolution (LTE) system of 3GPP standardization body can support FDD and TDD two kinds of dual-modes, and wireless frame structure comprises two kinds of frame structures of fdd mode and tdd mode.The frame structure of prior art fdd mode as shown in Figure 1, the radio frames (radioframe) of one 10 milliseconds (ms) is 0.5ms by 20 length, time slot (slot) composition of numbering 0 ~ 19, time slot 2i and 2i+1 forms the subframe i (subframe) that length is 1 millisecond, and uplink and downlink are respectively at the enterprising Serial Communication of different frequency resources.The frame structure of prior art tdd mode as shown in Figure 2; the radio frames of a 10ms is made up of two long fields (Halfframe) for 5ms; each field comprises the time slot and 3 special domain that 8 length are 0.5ms; these 3 special domain comprise descending pilot frequency time slot (DwPTS), protection interval (GP) and uplink pilot time slot (UpPTS), the length of these three special domain and be 1ms.Equally, in the frame structure of this tdd mode, subframe i is made up of two continuous print time slot 2i and 2i+1, and identical frequency spectrum resource is shared in uplink and downlink, and the different subframes respectively in radio frames carry out upstream or downstream communication.
In order to support non-symmetrical service, improving spectrum efficiency, the uplink-downlink configuration that 7 kinds different in existing LTE TDD system, can be supported, as shown in table 1, wherein, the D in table 1 represents descending sub frame, U represents sub-frame of uplink, and S representative comprises the special subframe of above-mentioned 3 special domain.
Table 1
In LTEFDD system, the frequency spectrum resource that subscriber equipment (UE) carries out communicating has symmetry, thus up-downgoing resource always can, make UE can feeding back uplink control signaling in time, as hybrid automatic repeat-request (HARQ, HybridAutomaticRetransmissionRequest) response message (ACK/NACK in, and CSI Acknowledge/Non-Acknowledge), thus the feedback delay of eating dishes without rice or wine of LTEFDD system can be reduced, improve dispatching efficiency.
Along with radio communication service explosion type and multifarious development, the design feature of the uplink and downlink asymmetry that communication service presents is more and more obvious.The reason of this asymmetry is caused to depend on many factors, may be correlated with Business Nature itself, such as, for the network video service that LTE system provides, download and browse and seriously will increase downlink traffic, and the social networks business provided for LTE system or point-to-point (P2P) communication service, then upstream traffic is just heavier.Therefore, in LTEFDD system, if time downlink traffic is many, so uplink frequency spectrum resource just compares and wastes.
Consider the feature of the asymmetric trend of future services, especially the needs of downlink business can exceed uplink service, in following wireless communication system, very possible TDD and FDD two dual-mode carries out flexible or used in combination in a system for different scenes, and then greatly provides the service efficiency of frequency spectrum and the performance of system.The part sub-frame of uplink that a kind of possible mixed structure is the uplink band in LTEFDD system or resource are shared by descending sub frame, or shared by the business of other non-cellular communication, such as, in current 3GPPRAN1 discusses, define a kind of equipment direct-connected (D2D, the DevicetoDevice) communication technology.According in the discussion of current RAN1 about the D2D communication technology, the D2D communication under LTEFDD MPS process takies ascending resource, and namely the uplink carrier frequencies of FDD community is the sub-frame of uplink of TDD cell.
For this structure flexibly, the uplink band of fdd mode can adopt the uplink-downlink configuration be similar in LTE TDD system or the uplink-downlink configuration redefined, by the reconfiguration technology of evolution base station (eNB), namely by the uplink-downlink configuration in the uplink band of dynamic signaling adjustment fdd mode, the ratio of current sub-frame of uplink and descending sub frame can be made more to meet current upstream traffic and downlink traffic, be conducive to improving the up-downgoing peak rate of UE and improve the throughput of system.
In LTE/LTE-A system, UE can obtain the channel condition information (CSI, ChannelStateInformation) of down channel according to downlink reference signal (referencesignal), then by obtain CSI feedback to eNB.The CSI that eNB feeds back according to UE, determines the modulation coding mode and the physical resource position that send to UE data, and transmission mode etc.CSI comprises four kinds of forms, channel quality instruction (CQI, ChannelQualityIndicator), pre-coding matrix instruction (PMI, Pre-codingMatrixIndicator), precoding type instruction (PTI, Pre-codingTypeIndicator), order instruction (RI, RankIndicator).In LTE/LTE-A system, the CSI feedback of UE to down channel has non-periodic feedback and periodic feedback, be called aperiodic channel status information (A-CSI, AperiodicCSI) to report and periodic channel state information (P-CSI, PeriodicCSI) report.A-CSI reports and refers to that eNB passes through to trigger signaling and triggers UE row shared channel (PUSCH physically, PhysicalUplinkSharedChannel) upper feedback CSI, its report condition is that UE receives descending control format instruction (DCI on descending sub frame, DownlinkControlIndicator) format0 or accidental access response license, corresponding channel quality instruction request (CQIrequest) or be " 01 " or " 10 " or " 11 " in DCIformat0, correspond to UE respectively and be operated in single cell scenario, be configured to transmission mode 1-transmission mode 9, or be configured to transmission mode 10, or under UE is operated in multiple cell scene, be configured to transmission mode 1-transmission mode 9, then the PUSCH that UE dispatches at this DCIformat0 send A-CSI and reports.P-CSI reports and refers to that UE configures according to eNB, the feedback CSI in row control channel (PUCCH, PhysicalUplinkControlChannel) upper cycle physically.Report for P-CSI, if UE does not send PUSCH in certain subframe, CSI transmits on PUCCH; If UE sends PUSCH, CSI and is carried on transmission on PUSCH.In the cycle that P-CSI reports and cycle, position skew is configured by high system level determine completely, and namely high-rise configuration parameter cqi-pmi-ConfigIndex is to UE, UE by tabling look-up, and can determine the concrete subframe position that CSI reports.For LTEFDD system, supported reporting cycle is 2/5/10/20/40/80/160, if be in discontinuous reception (DRX, DiscontinuousReception) pattern for UE, supported reporting cycle is 32/64/128; And for LTE TDD system, supported reporting cycle is 1/5/10/20/40/80/160.
For LTEFDD system, the corresponding sub-frame of uplink of each descending sub frame, the corresponding relation of this ascending-descending subframes presets, and notifies UE by eNB, i.e. uplink scheduling sequential relationship, comprises ACK/NACK feedback and CSI report.For LTE TDD system, uplink scheduling sequential relationship depends on the uplink-downlink configuration of cellular cell, supposes that UE receives PDCCH at descending sub frame n, then this PDCCH controls the PUSCH in sub-frame of uplink n+k, and the value of k defines in table 2 here.
Table 2
For this structure flexibly, the i.e. frame structure that taken by descending sub frame of the part sub-frame of uplink of the uplink band of fdd mode, mean that the part sub-frame of uplink that the uplink band of the band downlink of fdd mode and fdd mode is used as band downlink all can carry out downlink transfer, and only have a uplink band to be scheduled, be used for reporting the CSI of corresponding band, carry out downlink transmitting and dispatching for eNB.
Therefore, in this case, how to trigger and indicate A-CSI; How CSI request territory in corresponding Physical Downlink Control Channel (PDCCH, PhysicalDownlinkControlChannel) DCIformat0 defines; If the A-CSI that the descending sub frame in two frequency ranges in LTEFDD system triggers reports and reports on same sub-frame of uplink, and this CSI measured by two descending sub frames is positioned at different frequency ranges, the priority how between the CSI reporting A-CSI to distinguish measured by these two descending sub frames.In addition, because the part subframe in the uplink band of LTEFDD system is used as descending, then uplink scheduling relation cannot use at present, the need of CSI reporting cycle configuration that definition is new etc., the CSI having influence on UE reports by these problems, and then have influence on the downlink transfer of eNB, and finally have influence on the cell throughout of LTE system, not yet there is the solution for the problems referred to above at present.
Summary of the invention
In view of this, the embodiment of the present invention provides the method for reporting of a kind of CSI, and the method can ensure when in the occupied situation of part sub-frame of uplink in the uplink band in LTEFDD system, and the CSI report transmission of UE is unaffected.
The embodiment of the present invention also provides the report device of a kind of CSI, and this device can ensure when in the occupied situation of part sub-frame of uplink in the uplink band in LTEFDD system, and the CSI report transmission of UE is unaffected.

Conveniently describe, by the downlink transfer subframe of the band downlink of flexible FDD system referred to as FDD-DL, the subframe of uplink will be used as in the uplink band of flexible FDD system referred to as FDD-UL, change the part sub-frame of uplink in the uplink band of flexible FDD system into downlink transfer subframe referred to as FDD-UL-DL.
Embodiment one
Present embodiment describes UE and determine that whether triggering A-CSI at FDD-UL reports and indicate the method triggering the CSI reporting which frequency range.
During current RAN1 discusses, when dispatching the PUSCH of certain n-th+k subframe, eNB needs to send corresponding PDCCH in the n-th subframe and realizes this scheduling.For LTEFDD system, k equals 4, and for LTE TDD system, k depends on concrete ascending-descending subframes configuration relation.Whether UE triggers A-CSI on PUSCH is reported, and depends on the CSI request territory of DCI format in the PDCCH of corresponding carrying scheduling PUSCH information, or whether receives accidental access response request.Such as, when TDD system is configured to multi-antenna transmission pattern, DCIformat0 or DCIformat4.
In flexible FDD system, can transmitting downlink data on two carrier waves, so need the CSI that the descending sub frame in feedback two frequency ranges is reported.Therefore, A-CSI is reported, need to indicate the CSI corresponding frequency band of PUSCH carrying out A-CSI report, namely distinguish the CSI of the FDD-DL of triggering, or the CSI of FDD-UL-DL.
Suppose that eNB can send corresponding uplink scheduling request (UL-Grant) on FDD-DL and FDD-UL-DL.The UL-Grant frequency range that corresponding to the CSI a kind of PUSCH of instruction carrying out A-CSI report, the method for frequency range can receive according to UE is determined.Such as, UE on FDD-DL, receive UL-Grant and instruction triggers A-CSI report, then UE should report the CSI on FDD-DL; UE on FDD-UL-DL, receive UL-Grant and instruction triggers A-CSI report, then UE reports the CSI in FDD-UL-DL frequency range.
Suppose in flexible FDD system, eNB only sends corresponding uplink scheduling request UL-Grant on FDD-DL.The method of frequency range corresponding to the CSI a kind of PUSCH of instruction carrying out A-CSI report can according to the information field display instruction of UL-Grant.Such as, can be except CSI request territory, increase in UL-Grant 1 bit information indicate the A-CSI of current triggering to report for frequency range.Particularly, bit value 0 indicates the CSI triggering FDD-DL, and bit value 1 indicates the CSI triggering FDD-UL-DL.Or, also can be multiplexing existing information field indicate the A-CSI of current triggering to report for frequency range, such as, use code word non-in the carrier wave instructions field (CIF, Carrierindicator) of 3 bits.As shown in table 3, table 3 is a kind of methods of reporting frequency range based on code word non-in CIF territory instruction A-CSI.
Code word non-in CIF thresholding Describe
000 A-CSI for FDD-DL reports
001 A-CSI for FDD-ULDL reports
Table 3
Corresponding to the CSI another kind of instruction PUSCH carrying out A-CSI report, the method for frequency range indicates according to high level configuration or broadcast message.Such as, high-rise semi-static configuration or broadcast message, or physical layer signaling, or rrc layer signaling, inform UE and carry out A-CSI report for FDD-DL.
The method of frequency range corresponding to the CSI another kind of instruction PUSCH carrying out A-CSI report is the priority instruction according to downlink percent or two frequency range downlink business.Such as, the band downlink of flexible FDD system is for downlink transfer entirely, and in order to ensure the validity of the descending sub frame transmission of the band downlink of flexible FDD system, UE reports CSI corresponding to the descending sub frame of flexible FDD system on PUSCH.Such as, if the service priority that FDD-UL-DL carries is than high in FDD-DL subframe, then UE selects on PUSCH, carry out A-CSI and reports the CSI corresponded on FDD-UL-DL.
CSI request territory display instruction in DCIformat0 or format4 of the scheduling PUSCH that the method for frequency range receives according to UE corresponding to the CSI another kind of instruction PUSCH carrying out A-CSI report.Consider the display indicating means for CSI request territory under the UE single flexible community of configuration or multiple flexible community below respectively.
Suppose that UE only configures a flexible FDD community, FDD-DL and the FDD-UL-DL frequency range in flexible FDD community is considered as same community.Suppose that CSI request territory comprises 2 bits, then can use code word " 01 ", which " 10 " and " 11 " instruction triggers or the A-CSI of two frequency ranges reports, or reserved codeword need not.
Such as, can be indicate by code word " 01 " CSI triggering FDD-DL, trigger the CSI of FDD-UL-DL with code word " 10 " instruction, and trigger the CSI of one or more frequency range with high-level signaling instruction " 11 ", or " 11 " reservation not use.Table 4 shows the frequency range indicating means that a kind of A-CSI reports.
Table 4
Also such as, can be the CSI triggering FDD-DL with code word " 01 " instruction, and code word " 10 " and " 11 ", the CSI of one or more frequency range can be triggered with high-level signaling instruction.Table 5 shows the frequency range indicating means that a kind of A-CSI reports.

Suppose that UE is configured with multiple flexible FDD community, the FDD-DL frequency range in a flexible community and FDD-UL-DL frequency range are still considered as same community, under namely UE is operated in CA pattern.When UL-Grant is the PUSCH dispatching flexible FDD community, if UL-Grant triggers A-CSI and reports simultaneously, then " 01 " can be the CSI being defined as the FDD-DL triggering this flexible FDD community, or, also can trigger the CSI of FDD-DL and FDD-UL-DL of this flexible FDD community simultaneously." 01 " is predefined, also can be high-level signaling configuration.And " 10 " and " 11 ", can be configure with high-level signaling the CSI that it triggers which community and that frequency range.Table 6 shows the indicating means that a kind of A-CSI reports.

To above situation, if CSI request territory is 1 bit, can process according to " 01 " in dibit CSI request territory, namely " 1 " can be that the A-CSI being defined as the FDD-DL triggering this flexible community reports, or the A-CSI that also simultaneously can trigger FDD-DL and FDD-UL-DL of this flexible community reports.The definition of " 1 " can be predefined, is alternatively high-level signaling configuration.
Suppose two frequency ranges a flexible FDD community, namely FDD-DL and FDD-UL-DL is independently Liang Ge community, under UE is operated in CA pattern.Such as, can be defined as community corresponding to FDD-DL is first kind community, and being defined as community corresponding to FDD-UL-DL is Equations of The Second Kind community.When UL-Grant is the PUSCH of dispatching cell, report if trigger A-CSI simultaneously, then " 01 " can be defined as the A-CSI triggering first kind community to report, or the A-CSI that also simultaneously can trigger Equations of The Second Kind community reports.The definition of " 01 " can be predefined, also can be high-level signaling configuration.And can be the CSI that high-level signaling comes CSI and the FDD-UL-DL respective cell of configure trigger FDD-DL respective cell to " 10 " or " 11 ".Table 9 shows the indicating means that a kind of A-CSI reports frequency range.

So far, embodiment one terminates.In essence, This embodiment describes UE and determine that whether triggering A-CSI at FDD-UL reports and indicate the method triggering the CSI reporting which frequency range.UE determines instruction according to the frequency range receiving UL-Grant, or determine instruction according to the information field in the UL-Grant received, or by high-rise semi-static configuration or broadcast message, or physical layer signaling or rrc layer information, or according to the downlink percent of two frequency ranges or the priority character of downlink business, or shown by the CSI request territory in the PDCCH that receives and indicate whether that triggering A-CSI reports and corresponding frequency range.
Embodiment two
Present embodiment describes when the CSI on FDD-DL and FDD-UL-DL carries out A-CSI report at same FDD-UL, UE can only select a frequency range to carry out the method for A-CSI report.
Discuss according to existing RAN1, A-CSI reports and is carried on PUSCH.Suppose that the descending sub frame in existence two frequency ranges all can send uplink scheduling request, trigger and carry out corresponding CSI report on PUSCH.If high-rise configuration PUSCH resource can only carry the CSI in a frequency range, UE needs to select which frequency range to carry out A-CSI report according to certain priority criteria.
Fig. 7 for the embodiment of the present invention provide carry out A-CSI report time, a frequency range can only be selected to carry out the method flow diagram of A-CSI report, and its concrete steps are:
Step 701, UE receive CSI report information;
In this step, described CSI report information be carried at scheduling PUSCH PDCCH message and or configuration messages and or physical layer signaling or/and in rrc layer signaling; Described CSI report information can comprise CSI and report corresponding frequency range, and CSI reports type and/or CSI reports pattern, and/or CSI reports corresponding CSI process, and/or CSI reports corresponding cell carrier or CSI subframe collection.
Step 702, UE, according to the priority criteria arranged, select A-CSI to report corresponding frequency range.
Shown below is several preferred priority criteria for the present embodiment.Equally, a community whether is used as flexible FDD community below or Liang Ge community is considered respectively.
Two frequency ranges of flexible FDD community are supposed to be considered as a community.
If high level is configured with a flexible community for UE, the A-CSI of conflict is reported, need to determine that UE selects the A-CSI of which frequency range of transmission to report according to certain priority criteria.
A kind of method of PUSCH of instruction carrying out the corresponding frequency range of A-CSI report indicates according to high level configuration or broadcast message.Such as, high-rise configuration or broadcast message inform UE for LTEFDD system which band downlink carry out A-CSI report, if the value in corresponding CSI request territory is " 1 " or " 01 " or " 10 " or " 11 ".The configuration of this high level can be fixed configurations, also can be semi-static configuration.
A kind of method of PUSCH of instruction carrying out the corresponding frequency range of A-CSI report indicates according to the priority of downlink percent or two frequency range downlink business.Such as, a kind of priority is defined as the priority of FDD-DL higher than FDD-UL-DL, then UE selects on PUSCH, carry out A-CSI and reports the CSI corresponded in FDD-DL subframe.
The priority of the A-CSI report pattern of each frequency range that a kind of method of PUSCH of instruction carrying out the corresponding frequency range of A-CSI report configures according to high level indicates.In existing RAN1 discusses, A-CSI reports 3 kinds of report patterns, corresponds respectively to broadband CQI and reports, and the subband CQI that UE selects reports and the subband CQI of high-rise configuration reports.If distinguish the PMI pattern of reporting, have altogether corresponding to 5 kinds of different report patterns.Different transmission mode can support different report patterns, and performance objective corresponding to different report pattern requires different.Therefore, UE can carry out CSI report according to the priority between difference report pattern.Such as, high level is configured in the CSI that FDD-UL reports and corresponds to broadband CQI on FDD-DL, the CSI that FDD-UL reports corresponds to the subband CQI in FDD-UL-DL subframe, then UE selects on PUSCH, carry out A-CSI and reports the CSI corresponded on FDD-UL-DL.If the CSI request thresholding of correspondence is " 1 " or " 01 " or " 10 " or " 11 ".
A kind of priority criteria can also be determined according to the priority of the CSI process of CSI measurement correspondence.If configure multiple CSI process high-rise for UE, such as, high-rise configuration UE is the transmission mode of TM10, and UE needs measurement and returns the CSI information of multiple CSI process.Such as, the priority of priority higher than Equations of The Second Kind CSI process of first kind CSI process can be defined as, if then high level is configured on FDD-DL is first kind CSI process, and FDD-UL-DL is Equations of The Second Kind CSI process, according to priority, UE selects to report the CSI information that on FDD-DL, first kind CSI process is corresponding.
Priority joint instructions between the priority of the A-CSI report report pattern that a kind of method of PUSCH of instruction carrying out the corresponding frequency range of A-CSI report configures according to high level and frequency range.Namely UE first according to high level configuration the priority of carrying out the report pattern of A-CSI report in two frequency ranges first compare, if the report mode prioritization level of two frequency ranges is identical, then according to high level configuration carrier frequency/carrier wave between priority relationship judge.Such as, the broadband CQI of FDD-DL and FDD-UL-DL is all reported in high-rise configuration, and the priority of FDD-DL is higher than FDD-UL-DL priority, and namely two frequency ranges have identical report mode prioritization level, then UE selects the CSI reporting FDD-DL.
A kind of PUSCH of instruction carries out the priority joint instructions between the priority of the report pattern of the A-CSI report that method that A-CSI reports corresponding frequency range configure according to high level, CSI process index and frequency range.Such as, high level is configured to UE and is configured with multiple CSI process, and UE needs the CSI information of reporting multiple CSI process.The A-CSI of conflict is reported, UE first according to high level configuration A-CSI report pattern between priority first determine, if two frequency ranges have identical report pattern, compare CSI process index again, if the A-CSI of conflict has identical CSI process index, then judges according to the priority between frequency range.Such as: FDD-DL priority is higher than FDD-UL-DL.Such as, table 11 defines the priority approach that a kind of A-CSI reports.
Table 11
If high level is configured to UE and is configured with multiple community, under being operated in CA pattern.Report two A-CSI of conflict, the priority between the report pattern that the A-CSI that first UE configures according to high level reports first judges, if having identical report pattern, then compares CSI process index again; If have identical CSI process index; Compare CC index again, if conflict occurs between the different frequency range in same flexible community, then judge according to the priority between the different frequency range in flexible community again, such as: FDD-DL priority is higher than FDD-UL-DL.
Table 12 defines the priority approach that a kind of A-CSI reports.
Table 12
Table 13 defines the priority approach of another kind of A-CSI.
Table 13
Therefore, to conflict A-CSI, UE first according to high level configuration A-CSI report pattern between priority first judge, if having identical report pattern, then compare CSI process index again; If have identical CSI process index; Then judge according to the priority between the different frequency range in flexible community again, if frequency range is identical, then compare CC index again.Such as, FDD-DL index is 0, FDD-UL bin index is 1, when relatively frequency range, can specify that the priority of frequency range 0 is higher than frequency range 1.When relatively frequency range, to the FDD conventionally worked or TDD cell, can when relatively frequency band preference its bin index used of predefine, such as, fixingly to process according to frequency range 0.
Suppose using two frequency ranges of a flexible FDD community as two communities, under UE is operated in CA pattern.Such as, can be defined as community corresponding to FDD-DL is first kind community or member carrier CC#0, and being defined as community corresponding to FDD-UL-DL is Equations of The Second Kind community or member carrier CC#1.Therefore, the priority criteria of reporting the A-CSI of conflict can be continued to use existing priority criteria and judge.UE first according to high level configuration each community report pattern between priority judge.Identical report pattern is had, then more corresponding cell carrier index (CC index) again between Ruo Liangge community.Such as, table 14 gives a kind of method defining priority criteria.
Table 14
If high level is configured to UE and is configured with multiple CSI process, then UE needs the CSI information of reporting multiple CSI process.A-CSI for conflict reports, first UE reports pattern according to the CSI between the different districts of high level configuration, if having identical CSI to report pattern, then compares CSI process index, if conflict A-CSI reports have identical CSI process index, then judges according to the subcarrier index between community.Such as, table 15 gives a kind of method defining priority criteria.
First priority Second priority 3rd priority
The report pattern that A-CSI reports CSI process index Subcarrier index
Table 15
So far, this enforcement two terminates.Present embodiment describes when the CSI on FDD-DL and FDD-UL-DL same FDD-UL carry out A-CSI report time, UE, according to the priority criteria of high level configuration or physical layer signaling or the instruction of rrc layer signaling, selects to report the CSI in corresponding band.This priority criteria can according to the priority of frequency range, also can according to the priority two frequency ranges being transmitted downlink business.If two frequency ranges of flexible FDD community are considered as same community, high-rise basis can also be carried out the priority that A-CSI reports report pattern as required for UE is configured with a flexible native region priority criterion,
Corresponding CSI process index priority can also be reported according to the A-CSI that carries out of high level configuration, can also according to report pattern, the priority of CSI process index and frequency range determines jointly; Multiple flexible community is configured with for UE if high-rise, if priority criteria can also determine two frequency ranges of flexible FDD community to be considered as different districts according to subcarrier index priority, under high-rise configuration UE is operated in CA pattern, priority criteria can continue to use existing standard definition.Such as, decision is combined according to the carrier index of CSI report pattern, CSI process index, different districts.
Embodiment three
Present embodiment describes when the CSI on FDD-UL and FDD-UL-DL carries out A-CSI report in same FDD-UL subframe, UE at least reports the CSI in a frequency range.
Discuss according to existing RAN1, A-CSI reports and is carried on PUSCH.For a sub-frame of uplink, UE can be supported in the CSI this subframe transmitted from different descending carrier.For the duplex of FDD flexibly model, FDD-DL and FDD-UL-DL all can send uplink scheduling request, triggers and carry out corresponding A-CSI report on PUSCH.If when the PUSCH resource of high-rise configuration can carry or part carries the CSI on two frequency ranges or carrier wave, UE can select at least to report the CSI in a frequency range.For the CSI that UE reports, comprise CQI, PMI and RI.High level configuration UE can report this three kinds of information a PUSCH resource simultaneously, part CSI information can certainly be reported, PUSCH resource/uplink information the capacity depending on high-rise configuration and the total bit information number needing CSI to report, also depend on that the CSI reported in frequency range reports the priority of pattern.
Fig. 8 for the embodiment of the present invention provide carry out A-CSI time, select the method flow diagram that the part CSI in frequency range reports, its concrete steps are:
Step 801, UE receive CSI report information;
In this step, described CSI report information is carried at the scheduling PDCCH message of PUSCH, configuration messages, physical layer signaling or/and in rrc layer signaling; Described CSI report information can comprise CSI and report corresponding frequency range, and CSI reports type and/or CSI reports pattern, and/or CSI reports corresponding CSI process, and/or CSI reports corresponding cell carrier or CSI subframe collection;
Step 802, UE to calculate in each frequency range the information bit that corresponding CSI reports, according to the relation of information bit with up-link capacity, and/or the priority relationship of the CSI information report arranged, UE determines the CSI reported.
In this step, the priority relationship that CSI reports, can comprise the priority relationship determined according to CSI corresponding frequency band.Such as, the CSI of FDD-DL belongs to the first priority, and the CSI information of FDD-UL-DL belongs to the second priority.Also can comprise the priority relationship of the determination according to two frequency range downstream transmission business of high-rise semi-static configuration, also can comprise the priority relationship determined according to CSI pattern of reporting.
Such as: a kind of priority relationship can belong to the first priority for RI, and broadband CQI/PMI belongs to the second priority, sub-band CQI information belongs to the 3rd priority, as shown in table 16 below
First priority Second priority 3rd priority
RI Broadband CQI/PMI Subband CQI, subband CQI/PMI
Table 16
Above-mentioned priority relationship can be configured by high level, also can be predefined.Such as, standard has pre-defined a priority relationship table, and UE carries out determining that corresponding CSI reports in the mode of tabling look-up.
Below, the information bit reported for CSI and the relation of uplink channel capacity, and/or the different situations of the priority relationship of CSI information report, the method for UE being carried out to CSI report is specifically described.
Method 1: the priority relationship determined according to frequency range, such as, FDD-DL is better than FDD-UL-DL, and UE carries out the method for CSI report
According to the content of the CSI report information of high level configuration, UE calculates the information bit of two frequency range (FDD-DL and FDD-UL-DL) CSI respectively.
In existing RAN1 discusses, different report patterns, the CQI/PMI information bit of carrying is distinct.The information bit of CQI/PMI depends on the high-rise transmission mode, antenna port and the order information that configure.Such as, for transmission mode 4, or transmission mode 6, or the transmission mode 8, UE of carrying out PMI/RI feedback of high-rise configuration is carried out corresponding broadband CQI and is reported, and the information bit of corresponding CQI/PMI can be used shown in following table 17.
Table 17
Equally, the UE subband CQI/PMI of corresponding high-rise configuration reports, or the subband CQI/PMI that UE selects reports, and under different transmission modes, antenna port, order information configuration, the information bit number corresponding to corresponding CQI/PMI is all distinct.
Report for A-CSI, corresponding CQI/PMI is carried on up PUSCH, and upstream data, and/or HARQ-ACK, and/or RI, carries out multiplexing transmission.These three kinds of control informations (CQI/PMI, HARQ-ACK, RI) be carry out respectively code modulated.Such as, when high-rise configuration UE carries out A-CSI report, UE calculates the information bit of corresponding CQI/PMI according to concrete report type, and then after going out coded modulation according to formulae discovery below, required symbolic number is
Wherein, O is the bit number of the CQI/PMI information that corresponding needs are reported, and L is corresponding CRC check bit number, then corresponding bit number shared by CQI/PMI information is wherein for the modulation system of corresponding transmitted codewords.In above-mentioned formula, if high-rise configuration UE does not carry out RI report, then accordingly be characterized by for same code word, initially carry out the OFDM symbol number of PUSCH transmission. c (x), and obtain by the format0 in demodulation PDCCH or EPDCCH.
Corresponding upstream data, the modulation symbol number shared by it is G = N L ( x ) · ( N symb PUSCH · M sc PUSCH · Q m ( x ) - Q CQI - Q RI ( x ) ) , Wherein the number of plies required for transmitted codewords that table is corresponding, for present sub-frame scheduling for PUSCH transmission bandwidth, oFDM symbol number required for present sub-frame, its value equals wherein N sRSequal 0 or 1, depend on concrete SRS configuration.
Therefore, UE can need the report pattern of carrying out A-CSI report according to each frequency range of high level configuration, is gone out the information bit carried required for corresponding CQI/PMI by above-mentioned formulae discovery.
If CSI information bit corresponding to each frequency range is all less than the capacity of physical uplink channel.Here, the bit number that the capacity of physical uplink channel can be able to carry for the maximum ascending control information carried of high-rise configuration, such as, PUCCHformat3, its supported heap(ed) capacity is 22 bits.The total bit number of CSI information corresponding to two frequency ranges is also less than or equal to uplink channel capacity, and the PUSCH that CSI corresponding in two frequency ranges can be carried on FDD-UL subframe by UE simultaneously carries out multiplexing transmission.
If CSI information bit corresponding to two frequency ranges is all less than physical uplink channel capacity, and total bit number is greater than physical uplink channel capacity, UE, according to priority relationship, preferentially can report CSI corresponding to FDD-DL, abandons reporting CSI corresponding to FDD-UL-DL; Also CSI corresponding to FDD-DL can first be reported, residual capacity reports the high information of CSI medium priority corresponding to FDD-UL-DL, such as, if high-rise configuration needs to report RI and the information bit of RI in the CSI of CSI and the FDD-UL-DL of FDD-DL is less than or equal to physical uplink channel capacity.For the CSI that the frequency range of not reporting is corresponding, the information such as MCS, PMI that eNB is required when dispatching the upper downlink transfer once in corresponding frequency band, still continue to use the relevant information during downlink transfer in current frequency range.
If be all greater than physical uplink channel capacity in the CSI that two frequency ranges are corresponding, UE, according to priority relationship, can report the information that CSI priority corresponding in FDD-DL is high, as RI or broadband CQI, abandons reporting CSI corresponding to FDD-UL-DL.Equally, for the CSI that the frequency range of not reporting is corresponding, the information such as MCS, PMI that eNB is required when dispatching the upper downlink transfer once in corresponding frequency band, still continue to use the relevant information during downlink transfer in current frequency range.
Method 2, report according to CSI the method that the priority determined of pattern carries out CSI report:
According to the content of the CSI report information of high level configuration, UE calculates the information bit of two frequency range (FDD-DL and FDD-UL-DL) CSI respectively.
If CSI information bit corresponding to two frequency ranges is all less than physical uplink channel capacity, and total bit number is also less than or equal to physical uplink channel capacity, the PUSCH that CSI corresponding in two frequency ranges can be carried on FDD-UL by UE simultaneously carries out multiplexing transmission.
If CSI information bit corresponding to two frequency ranges is all less than physical uplink channel capacity, and total bit number is greater than physical uplink channel capacity.UE, according to priority relationship, first reports the CSI in priority high corresponding frequency band.Such as, high-rise configuration needs CSI on configuration FDD-DL to be subband CQI, and to configure CSI on FDD-UL-DL be RI and broadband CQI, UE preferentially can report the CSI on FDD-UL-DL, abandon reporting the CSI on FDD-DL, also first can report CSI corresponding to FDD-UL-DL, residual capacity reports the high information of CSI medium priority corresponding to FDD-UL-DL.Equally, for the CSI that the frequency range of not reporting is corresponding, the information such as MCS, PMI that eNB is required when dispatching the upper downlink transfer once in corresponding frequency band, still continue to use the relevant information during downlink transfer in current frequency range.
If be all greater than physical uplink channel capacity in the CSI that two frequency ranges are corresponding, UE, according to priority relationship, can report the information that CSI priority corresponding in FDD-DL is high, as RI or broadband CQI, abandons reporting CSI corresponding to FDD-UL-DL.Equally, for the CSI that the frequency range of not reporting is corresponding, the information such as MCS, PMI that eNB is required when dispatching the upper downlink transfer once in corresponding frequency band, still continue to use the relevant information during downlink transfer in current frequency range.
So far, the present embodiment terminates.Describe same sub-frame of uplink PUSCH in essence, carry the CSI in two frequency ranges, UE is according to the total bit number of corresponding CSI information and the high-rise uplink channel capacity relation configured, and/or report priority relationship, complete CSI or part CSI in selectable report frequency range, or report complete CSI or part CSI in two frequency ranges.
Embodiment four
Present embodiment describes when the P-CSI of FDD-DL and FDD-UL-DL reports needs in same FDD-UL report, UE carries out the method for P-CSI report.
Discuss according to existing RAN1, P-CSI reports and is carried on PUCCH.For a sub-frame of uplink, UE is only supported in the CSI this subframe transmitted from a descending carrier.Report for P-CSI, CSI comprises CQI, PMI, RI and PTI information.In R8/R9LTE system, the P-CSI that can be respectively single frequency range configuration RI and CQI/PMI reports, and it is on the middle and senior level by configuration parameter ri-ConfigIndex (I rI) decide, can configuration cycle M rIwith side-play amount N oFFSET, RIp-CSI report is carried out to UE.Equally, high-rise by configuration parameter cqi-pmi-ConfigIndex (I cQI/PMI) decide, can configuration cycle N pdwith side-play amount N oFFSET, CQIcQI/PMI report is carried out to UE.
For LTEFDD system flexibly, namely FDD-DL and FDD-UL-DL all can carry out downlink transfer, FDD-UL need configure respectively RI corresponding in above-mentioned two frequency ranges reports and CQI/PMI reports cycle and report side-play amount.Therefore, when the P-CSI of two frequency ranges reports conflict, when being namely mapped to same sub-frame of uplink, needing to decide UE according to certain priority criteria and select the P-CSI sending which frequency range to report.Here, the method how defining the criterion of priority can have multiple consideration.Two frequency ranges of a flexible FDD community are considered still to describe as Liang Ge community to define priority criteria as same community below respectively.
Two frequency ranges of a flexible FDD community are supposed to report as same community process P-CSI.
A kind of priority criteria can be determined according to frequency range.Such as, the priority of FDD-DL can be defined higher than FDD-UL-DL.The determination of this priority relationship by the semi-static configuration of high level, or is configured by physical layer signaling or RRC signaling, or by indicated by broadcast message.
A kind of priority criteria can be determined according to the priority of downlink percent or two frequency range downlink business.Such as, the band downlink of flexible FDD is for downlink transfer entirely, and in order to ensure the validity of the descending sub frame transmission of the band downlink of flexible FDD system, UE reports CSI corresponding to the descending sub frame of flexible FDD system on PUSCH.Such as, or the service priority that FDD-UL-DL carries is higher than FDD-DL subframe, then UE selects on PUSCH, carry out A-CSI and reports the CSI corresponded on FDD-UL-DL.
A kind of priority criteria can also be determined according to the priority of the CSI process of CSI measurement correspondence.If configure multiple CSI process high-rise for UE, such as, high level is configured to UE and is configured in transmission mode TM10, and UE needs measurement and returns the CSI of multiple CSI process.Such as, the priority of priority higher than Equations of The Second Kind CSI process of first kind CSI process can be defined as, if then high level is configured on FDD-DL is first kind CSI process, and FDD-UL-DL be Equations of The Second Kind CSI process, according to priority, UE selects to report CSI corresponding on FDD-DL.
Report for P-CSI, existing standard defines 4 kinds of report patterns.Such as, report pattern 1-0 and be expressed as broadband CQI and without PMI, report the broadband CQI that pattern 1-1 is expressed as single PMI, report pattern 2-0 and represent subband CQI and without PMI, report pattern 2-1 and represent subband CQI and single PMI.Report pattern for these four kinds, standard definition can support that altogether 10 kinds are reported type, as shown in table 16 below.
Table 18
The report type supported under different report pattern is distinct.Such as, report pattern 1-0 and comprise report type (3,4), report pattern 1-1 comprises report type (3,5,2,2b, 2c), report pattern 2-0 and comprise report type (1,3,4) report pattern 2-1 and comprise report type (1,1a, 2,2a, 2b, 3,6).
Therefore, the report pattern that configures according to high level of a kind of priority criteria or the priority of reporting between type are determined.Define in existing standard, when being configured in a community for UE, if the CSI of UE reports type (3,5 in high-rise configuration service community c, 6) with the report type (1 of UE in same Serving cell c, 1a, 2,2a, 2b, 2c, 4), when being mapped to same sub-frame of uplink, the former priority is higher than the latter.If be configured with multiple CSI process high-rise for UE, if CSI report type corresponding to multiple CSI process has identical priority, then more corresponding again CSI process index priority, what CSI process index index was minimum has high priority.Therefore, priority criteria can configure according to high level and determine to the priority between the report type of FDD-DL or FDD-UL-DL or CSI process index.Such as, the RI (reporting type 3) of FDD-DL is reported in high level configuration, and reports the broadband CQI (reporting type 4) of FDD-UL frequency range, then UE preferentially carries out the P-CSI report of FDD-DL.Such as, the CSI process index that high-rise configuration UE is used for the CSI measurement correspondence of FDD-DL is first kind CSI process, the CSI process index that UE is used for the CSI measurement correspondence of FDD-UL-DL frequency range is Equations of The Second Kind CSI process, then UE preferentially carries out first kind CSI process, and namely the P-CSI of FDD-DL frequency range reports.Here, the frequency range of flexible FDD community is indicated by the index of CSI process.
Two P-CSI of conflict are reported, supposes not distinguish priority criteria by CSI process, so can by directly reporting corresponding bin index definition priority according to CSI.Specifically, report the P-CSI of conflict, the priority between the report type that the P-CSI that first UE configures according to high level reports judges; If have identical report type, then judge according to the priority between the different frequency range in flexible FDD community, such as, the priority of FDD-DL is higher than FDD-UL-DL again.
Two P-CSI for conflict report, and also distinguish priority criteria by CSI process.If two frequency ranges, the report type of configuration has identical priority, then CSI process index that can be more corresponding, is configured with multiple CSI process if high-rise for UE; If the CSI process index of two frequency ranges is identical, then can distinguish according to the priority between frequency range, such as, the priority of FDD-DL is higher than FDD-UL-DL.Following table 19 gives a kind of method defining priority criteria.
First priority Second priority 3rd priority
The report type that P-CSI reports CSI process index The different frequency range of same flexible FDD community
Table 19
Or, between different report patterns, also there is dividing of priority.Such as, that report pattern 1-0 reflects is broadband CQI, and report the broadband CQI for single PMI of pattern 1-1 reflection, the priority of report pattern 1-0 can be defined higher than report pattern 1-1, the priority of report pattern 1-1, higher than report pattern 2-0, reports the priority of pattern 2-0 higher than report pattern 2-1.Therefore, report two P-CSI of conflict, the priority that first UE reports between report pattern according to the P-CSI of high level configuration first judges.If have identical report pattern, then compare CSI process index again; Then judge according to the priority between the different frequency range in flexible FDD community, such as, the priority of FDD-DL is higher than FDD-UL-DL again.Therefore, following table 20 gives a kind of method defining priority criteria.

Therefore, the P-CSI of conflict is reported, priority between the report type that the P-CSI that first UE configures according to high level reports first judges, if have identical report type, again than higher level configuration report pattern between priority, if have identical priority, then compare CSIp process index again; If have identical CSI process index; Then judge according to the priority between the different frequency range in flexible community again, such as: FDD-DL priority is higher than FDD-UL-DL.
Or, define in existing standard, if high level is configured to UE be configured with multiple community, when P-CSI between community reports and clashes, if the CSI between different districts reports type have identical priority, then determine according to CC index, what CC index index was low has high priority again.If high-rise UE is configured with multiple community and multiple CSI process, if the CSI between different districts reports type have identical priority, then CSI process index that can be more corresponding, CSI process index has high priority.Therefore, report the P-CSI of conflict, the priority that first UE reports between type according to the cycle CSI of high level configuration first judges, if having identical report type priority level, then compare CSI process index again, if have identical CSI process index, then compare CC index again, if it is corresponding same flexible FDD community that the P-CSI of conflict reports, then compare frequency range again, determine according to the priority between frequency range, such as, the priority of FDD-DL is higher than FDD-UL.Following table 22 gives a kind of method defining priority criteria.

Therefore, report the P-CSI of conflict, the priority between the report type that the P-CSI that first UE configures according to high level reports first judges.If two frequency ranges have identical report type, then the report pattern belonging to more corresponding again, if two frequency ranges have identical report pattern, then compares CSI process index again, if having identical CSI process index, then at relatively CC index; If have identical CC index, if the CSI of conflict is corresponding same flexible FDD community, then compare frequency range again; If have identical frequency range, then compare CSI subframe collection index, such as, CSI subframe collection 0 priority is higher than CSI subframe collection 1.
Suppose using two frequency ranges of a flexible FDD community as two communities, under UE is operated in CA pattern.
Such as, suppose that UE is only configured with a flexible FDD community, the CA system that UE can be made to form according to Liang Ge community carrys out work.Liang Ge community mentioned here refers to FDD-DL and FDD-UL of flexible FDD community.Can be defined as community corresponding to FDD-DL frequency range is CC#0, is equivalent to Pcell; And to define community corresponding to FDD-UL frequency range be CC#1, or CC index high-level signaling corresponding to FDD-UL configures.Suppose that UE is configured with multiple community, and comprise at least one flexible FDD community, the CA system that UE can be made to form according to multiple community carrys out work.Wherein, FDD-DL and FDD-UL of each flexible FDD community processes according to a community respectively.At this moment, can be define CC index corresponding to FDD-DL and FDD-UL respectively with high-level signaling, or, also can be community corresponding to high-level signaling configuration FDD-DL frequency range be CC index, being designated as k, be CC index is k+1 from the community that regulation FDD-UL-DL frequency range is corresponding.
After two frequency ranges of flexible FDD community being treated to Liang Ge community respectively according to method above, report the P-CSI of conflict, it can be continued to use existing priority criteria and carry out judgement priority.UE first according to high level configuration each community report type between priority judge.There is identical priority between Ruo Liangge community, then compare CSI process index, if having identical CSI process index, then more corresponding cell carrier index (CC index) again.Such as, following table 30 gives a kind of method defining priority criteria.
First priority Second priority 3rd priority
The report type of P-CSI CSI process index Carrier index
Table 30
Following table 31 gives another method of definition prioritization criteria

Therefore, the priority criteria of reporting conflict P-CSI can be continued to use existing priority criteria and judge.Such as, high level is configured to UE configuration effort under CA pattern, and high level is configured to UE and is configured with multiple community and multiple CSI process.When P-CSI report clash time, UE first according to high level configuration each community report type between priority judge.Identical priority is had between Ruo Liangge community, then compare the report pattern that P-CSI reports, if having the report pattern of identical P-CSI report, then compare CSI process index again, if have identical CSI process index, then corresponding cell carrier index (CC index) of comparing again.
So far, the present embodiment four terminates.In essence, This embodiment describes when the P-CSI report of the different frequency range of high-rise configuration clashes, according to certain priority criteria, UE determines that the P-CSI of configuration reports mode.If two of flexible FDD frequency ranges are used as a community, when configuration clashes to the P-CSI of two frequency ranges report, the priority relationship that priority criteria can be determined according to the semi-static configuration of high level or physical layer signaling or rrc layer signaling is determined, also can determine according to downlink percent or two frequency range downlink business priority relationship, between the report type that also can configure to two frequency ranges according to high level, priority is determined, also can determine to the priority of the report pattern of two frequency ranges according to high level, also can determine to the priority between the CSI process of two frequency ranges according to high level, also can determine according to the priority of two frequency ranges according to same flexible FDD community.If high-rise configuration UE is operated in multiple community, two frequency ranges of FDD community are still used as a community flexibly, corresponding priority criteria can also be determined according to the priority of carrier index, the report type that the P-CSI that can also combine high-rise configuration reports, the report pattern that P-CSI reports, CSI process index, the priority of the one or more combinations in the frequency range of carrier wave CC index, CSI subframe collection index and same flexible FDD community is determined.If two of flexible FDD frequency ranges are used as Liang Ge community, when clashing P-CSI report, corresponding priority criteria defining method can continue to use the definition of existing standard.Such as, can determine according to the priority of the report type between the different districts of high level configuration, also can determine according to the priority of the CSI process index between the different districts of high level configuration, also can determine according to the carrier index priority between different districts.
For FDD dual-mode flexibly, the UL frequency range of FDD can adopt different uplink and downlink timeslot proportionings.One method is employing is period allocated ascending-descending subframes with 10ms.The 10ms frame structure of the method and existing LTE system is consistent, thus can simplify relevant standardization and the complexity of UE.Such as, this 10ms frame structure still adopts existing TDD uplink and downlink timeslot to configure 0-6, but under this configuration, limits sub-frame of uplink available at most in this frequency range.Therefore, consider if when uplink service is many, the ascending time slot number in this frequency range can be increased.Such as, under existing TDD uplink-downlink configuration, extra increase by 5 kinds of configurations, support that sub-frame of uplink number is 0,7,8,9,10.Certainly, another kind of method is the wireless wireless frame structure being not limited to 10ms, but adopts other ascending-descending subframes distribution repetition period.Owing in existing LTEFDD system being the winding time delay (RTT of the HARQ adopting 8ms, RoundTripTime), therefore, in order to mate with the HARQRTT of LTEFDD system, the ascending-descending subframes distribution of the UL frequency range of a kind of FDD can adopt the cycle of 8ms to distribute.Equally, for the value partly or completely that to take 8ms as the sub-frame of uplink number of distributing within each cycle in the cycle can be from 0 to 8, as shown in Figure 9, a kind of possible uplink and downlink timeslot proportioning allocation plan that Fig. 9 provides for the embodiment of the present invention, the design principle of this configuration is that continuous print distributes up or descending time slot, reduces the conversion times of up-downgoing as much as possible.The embodiment of the present invention does not limit concrete uplink and downlink timeslot proportion relation.In existing 3GPP standard, P-CSI reports and is carried on PUCCH.In R8/R9LTE system, the P-CSI that can be respectively single frequency range configuration RI and CQI/PMI reports, and it is on the middle and senior level by configuration parameter ri-ConfigIndex (I rI) decide, can configuration cycle M rIwith side-play amount N oFFSET, RIp-CSI report is carried out to UE.Equally, high-rise by configuration parameter cqi-pmi-ConfigIndex (I cQI/PMI) decide, configuration cycle N pdwith side-play amount N oFFSET, CQIcQI/PMI report is carried out to UE.High-rise by these parameter configuration to UE, UE by tabling look-up, and then determine the concrete subframe position that CSI reports.For FDD system, the reporting cycle of CQI/PMI can be configured to 2/5/10/20/40/80/160, if be in discontinuous reception DRX mode for UE, supported reporting cycle is 32/64/128; And for TDD system, the supported reporting cycle of CQI/PMI is 1/5/10/20/40/80/160.Because the part subframe in the uplink band of FDD system is used as descending, then original up timing relationship be not suitable for.Therefore, for FDD dual-mode flexibly, when the uplink band of FDD system is occupied be used as downlink transfer time, the cycle needing definition or amendment to report about P-CSI and side-play amount configuration.
Two preferred embodiments of cycle and the side-play amount configuration of reporting about P-CSI are described below.
Embodiment five
When present embodiment describes the frame structure as the uplink band employing 10ms of FDD system, the cycle that P-CSI reports and side-play amount collocation method.
When up-downgoing proportioning in the uplink band of FDD system adopts the frame structure of 10ms, in the reporting cycle of original FDD system configuration CQI/PMI, the such as cycle is 2, or 32/64/128 unavailable, because existence can cause on some position, present sub-frame is descending sub frame and can not carries out P-CSI report.Such as, when being configured to of uplink and downlink timeslot ratio in the uplink band of FDD continues to use the configuration 1 in TDD configuration, as shown in Figure 10, uplink and downlink timeslot in the uplink band of the FDD that Figure 10 provides for the embodiment of the present invention is than structure one schematic diagram, if high-rise configuration cqi-pmi-ConfigIndex (I cQI/PMI) when being 1, corresponding cycle N pd=2 and side-play amount N oFFSET, CQI=1, then the subframe that UE carries out CQI/PMI report must meet
Wherein, n ffor the sequence number of radio frames, n sfor the timeslot number in this radio frames, then the subframe numbers in respective wireless frame is subframe 1/3/5/7/9, and 4/9 is descending sub frame, can not be used for CQI/PMI and report.Therefore, the new P-CSI reporting cycle of definition and side-play amount collocation method is needed.As table 32 gives a kind of possible configuration example, the period assignment that the cycle CQI/PMI of TDD structure reports can be adopted.
Table 32
Wherein, the cycle be 1 configuration be applicable to TDD uplink-downlink configuration in 0,1,3,4,6}, and all sub-frame of uplink all may be used for CQI/PMI report.
So far, the present embodiment terminates.When present embodiment describes the 10ms frame structure configuration of uplink and downlink timeslot configuration employing TDD system in the uplink band of FDD system, the cycle of P-CSI report can adopt the period assignment of TDD structure.
Embodiment six
Present embodiment describes when the uplink band of FDD adopts 8ms to be the repetitive structure in cycle, the cycle that P-CSI reports and side-play amount collocation method.
When up-downgoing proportioning in the uplink band of FDD adopts 8ms to be the repetitive structure in cycle, then original FDD configures the reporting cycle of CQI/PMI, and the such as cycle is 2, or is not the multiple of 8, and the CQI/PMI that can not be used for the cycle of carrying out reports.New equipping rules needs to follow the repetition feature and concrete uplink and downlink timeslot relation that 8ms is the cycle.
In order to ensure the UE communication under normal FDD frame structure, the uplink band for FDD still continues to use 10 subframes, forms a radio frames, adopts 8ms to be the repetitive structure in cycle in frame.Least common multiple due to 10 and 8 is 40, therefore, and repeating once of each 4 radio frames.If n ffor the sequence number of radio frames, namely have and meet n ffirst subframe and the subframe of 8ms change-over period 0 of the radio frames of mod4=0 are alignd.Therefore, high-rise report by configuration CQI/PMI configures I cQI/PMI, then the subframe that the CSI that UE carries out the cycle reports need meet relation below:
Wherein, n ffor the sequence number of uplink frame, ns is the timeslot number in uplink frame.
Table 33 gives a kind of possible collocation method example.Such as, if the uplink and downlink timeslot proportioning of the uplink band of FDD is for shown in Figure 11, high-rise configuration I cQI/PMIcSI when=2 reports scheme.
Table 33
Embodiment seven
Present embodiment describes when the uplink band of FDD adopts 8ms to be the repetitive structure in cycle, the distribution method of CSI-RS.
Define in existing 3GPP standard, the assignment period of CSI-RS is the multiple of 5ms, when according to 8ms period assignment ascending-descending subframes, can cause on some position, can not distribute CSI-RS because present sub-frame is sub-frame of uplink, or present sub-frame is descending sub frame and can not transmitting SRS.
Distribution method can for defining a new assignment period, and such as, assignment period is the multiple of 4ms.Therefore, the high-rise subframe position I by configuration CSI-RS cSI-RS, then the CSI-RS that UE carries out the cycle carries out measurement subframe and need meet relation below:
Wherein, n ffor the sequence number of uplink frame, n sfor the timeslot number in uplink frame.
Table 34 gives a kind of distribution method of possible CSI-RS.
Table 34
So far, the present embodiment terminates.Present embodiment describes when the uplink band of FDD adopts 8ms to be the repetitive structure in cycle, needs definition take 4ms as the CSI-RS distribution method of multiple.
